Step 1: figure out what paths are included in current notebook session

import sys
print(sys.path)

Step 2: figure out where your package is installed

!pip show YOUR_PACKAGE

Make your the path in Step 2 is included in Step 1 list. If not, try:

!pip install --target=d:\some\path\thats\in\step1\list YOUR_PACKAGE

Just in case someone is meeting a similar problem to mine. Pay attention to the case of the package. In my case, the package is called 'shapely'. And I installed it through

pip install Shapely

But you have to import as

import shapely

I met the same problem, but in my case the package is created by myself. So this answer applyes to the custom packages. See Why customer python package can not be imported? for details.

Python looks for its modules and packages in $PYTHONPATH. You'll need to figure out if the __init__.py module of the package you'd like to use is in python's path. To find out whether it is in python's path, run:

    import sys
    print(sys.path)

within python.

To add the path to your module, run:

sys.path.append("/path/to/your/package_or_module")

and you should be set.
